Mr. Richards has been a tax attorney for more than twenty years beginning his career with the IRS where he was a leading trial attorney, a Chief Counsel advisor, and a Special Assistant United States Attorney.

He understands the tax system, provides informed advice, and protects taxpayers from the mistakes and missteps of those less experienced. Several years after leaving the IRS, he represented a Colorado cannabis company in one of the first IRS audits in the legalized industry.

In addition to tax audits, trials and collections, he is widely recognized as a leading cannabis industry attorney and has extensive experience in IRC Section 280E and BSA cash reporting requirements.
